UNITED STATES CHRISTOPHER O. JONES, OF SAVANNAH, GEORGIA, ASSIGNOR OF ONE-HALF TO J. S. COLLINS,

OF SAME PLACE.

CAR-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 596,030,'dated December 21, 1897. Application filed February 16, 1897. Serial No. 623 ,63'7. (No model.)

To all whom it may concern.-

- Be it known that I, CHRISTOPHER O. J ONES, a citizen of the United States, residing at Savannah, in the county of Ohatham and State of Georgia, have invented a new and useful Car-Signal, of which the following is a specification.

This invention aims to provide an automatic signal-bell for steam or street railway cars and for general use wherever it is required to provide an audible signal combining a gong-bell and hammer, the signal be-.

ing operated either by hand or from a moving part of the car, vehicle, or element to which the bell may be applied.

While the invention is designed for general application, it will be shown in connection with the truck of a street-car and adapted to be operated from either an axle or the brakeshaft. A

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the ad-' Figure 1 is a side elevation of an end portion of a car-truck, showing the invention applied thereto. Fig. 2 is a detail view, on a larger scale, showing the bell arranged to be operated by means of a brake-shaft. Fig. 3 is a detail View showing the bell arranged to be operated from an axle. Fig. 4. is a detail View of the plate or pulley supporting the gong-bell, hammers, and buffers. Fig. 5 is a front view of the gong-bell, showingthe openings thereinfor the escape of the sound. Fig. 6 is'a detail view of the bracket which connects the hangers with the car-truck.

Corresponding and like parts are referred to in the following description and indicated in the several views of the accompanying drawings by the same reference-characters. The gong-bell 1 is secured toa plate or pulley 2 by means of a central support 3, which is preferably of tubular form and has its base portion flaring, so as to secure an extended bearing again st the pulley or plate, to which it is attached in any convenient way. In order to prevent a muffled sound and to admit of the latter escaping, the bell is formed with a series of openings 4, which are grouped about a central point in such a manner as not to interfere with the resonant qualities of the bell. The plate or pulley 2 maybe of any desired formation, either solid. or open, the latter construction being preferred for the sake of lightness and also to provide for the escape of the sound vibrations. A series of pins 5 are secured to the plate or pulley 2 and support a corresponding number of hammers 6, which are mounted so as to oscillate freely thereon. The arms of. the hammers are curved away from the plate, so as to admit of the hammers extending within the gong-bell, so as to strike against the inner side thereof. A pair of stops 7 are provided for each hammer and are located upon opposite sides of the pin 5, so as to limit the movements of the hammer, and these stops are rubber blocks or buffers to prevent any noise or clatter when thehammersimpactthereagainst. Thehammers are of such length as to swing past the support 3, so as to strike the bell upon either side of the pins upon which the respective hammers are mounted. The pulley or plate 2 is rotatably mounted, thereby causing an oscillatory movement of the hammers, which latter, striking against the gong-bell, produce a sound, so as to warn any one of the approach of the car, vehicle, or other contrivance to which the bell may be applied.

As shown most clearly in Fig. 2, the plate or pulley is secured to the inner end of a shaft 8, which is mounted in bearings provided on a bracket 9, secured to and pendent from the platform of a car, and the front end of this shaft has a bevel-pinion 10, which meshes with a bevel-wheel 11, secured to the brake-shaft 12. Hence upon operating the brake-shaft either to apply or release the brakes the shaft 8 is rotated, likewise the bell attached thereto,whereby a sound is produced to serve as a warning to any one of the stopping or starting of the car or Vehicle, as the case may be.

As seen most clearlyin Fig. 3, the plate or ICO pulley 2 is rotatablymounted upon a spindle 13 of a hanger 14, having a journal 15 at its opposite end, mounted in a bracket 16, secured to the floor or platform of the car. A corresponding hanger 17 has a journal 18 at one end, mounted in the bracket 16, and is provided at its opposite end with a spindle 19, bearing a flanged pulley20, which is in frictional engagement with an axle 21 and with the pulley or plate 2, thereby serving as a means for transmitting motion from the axle 21 to the pulley 2, so as to sound the bell. The central portion of the pulley 20 is reduced and its heads or flanges are of greater diameter than the reduced portion and engage 'with the axle 21, thereby rotating the pulley or plate 2 at adiminished speed, more so than would result if the pulley 2 engaged directly with the axle 21. The hangers 14 and 17 incline from the perpendicular, thereby causing the parts 2, 20, and 21 to engage by gravity and leaving them free to swing about their respective journals 15 and 18, whereby the hammers are adapted to be operated bythe rotary movement of the plate 2 and by the vibration of the said plate with its hanger 14.

Having thus described the invention, what is claimed as new is- 1. In combination, a rotatable support, a plate secured to and rotatable with the said support, a gong-bell carried by the plate, and vibrating hammers carried by the plate and adapted to strike against the gong-bell, substantially as set forth.

2. In combination, a swinging hanger, a plate or pulley journaled upon a spindle at the free end of the hanger, a gong-bell carried by the plate, and vibrating hammers supported by the plate and adapted to strike against the gong-bell, substantially as set forth.

3. In combination, an axle, a swinging hanger, a pulley journaled upon-a spindle of the swinging hanger, a gong-bell and hammers attached to the pulley, and means for transmitting motion from the axle to the said pulley, substantially as and for the purpose set forth.

4. In combination, a swinging hanger, a pulley j ournaled upon a spindle of the hanger and bearing a gong-bell and hammers, an axle, and a flanged pulley for transmitting motion from the axle to the pulley, substantiall y as set forth.

5. In combination, an axle, a swinging hanger, a pulley mounted upon a spindle of the hanger and bearing a gong-bell and hammers,a,seeond swinging hanger, and a flanged pulley mounted upon a spindle of the second hanger and arranged to transmit motion from the axle to the aforesaid pulley, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

CHRISTOPHER C. JONES.
